Examples
Line Chart

NKBarChart *chart = [[NKBarChart alloc] initWithFrame:frame]; chart.yLabelFormatter = ^(CGFloat yValue){ CGFloat yValueParsed = yValue; NSString * labelText = [NSString stringWithFormat:@"%0.f",yValueParsed]; return labelText; }; chart.labelMarginTop = 5.0; chart.showChartBorder = YES; [chart setXLabels:@[@"2",@"3",@"4",@"5",@"2",@"3",@"4",@"5"]]; // self.barChart.yLabels = @[@-10,@0,@10]; [chart setYValues:@[@10.82,@1.88,@6.96,@33.93,@10.82,@1.88,@6.96,@33.93]]; [chart setStrokeColors:@[NKGreen,NKGreen,NKRed,NKGreen,NKGreen,NKGreen,NKRed,NKGreen]]; image = [chart drawImage]; [self.chartImage setImage:image];Pie Chart
NSArray *items = @[[NKPieChartDataItem dataItemWithValue:10 color:NKLightGreen], [NKPieChartDataItem dataItemWithValue:20 color:NKFreshGreen description:@"WWDC"], [NKPieChartDataItem dataItemWithValue:40 color:NKDeepGreen description:@"GOOG I/O"], ]; NKPieChart *chart = [[NKPieChart alloc] initWithFrame:frame items:items]; chart.descriptionTextColor = [UIColor whiteColor]; chart.descriptionTextFont = [UIFont systemFontOfSize:12.0]; chart.showAbsoluteValues = NO; chart.showOnlyValues = NO; image = [chart drawImage]; [self.chartImage setImage:image];
Circle Chart
UIColor *shadowColor = [UIColor colorWithRed:225.0 / 255.0 green:225.0 / 255.0 blue:225.0 / 255.0 alpha:0.5f]; NKCircleChart *chart = [[NKCircleChart alloc] initWithFrame:frame total:@100 current:@60 clockwise:YES shadow:YES shadowColor:shadowColor displayCountingLabel:YES overrideLineWidth:@5]; chart.strokeColor = NKGreen; chart.strokeColorGradientStart = NKLightGreen; image = [chart drawImage]; [self.chartImage setImage:image];
Radar Chart
NSArray *items = @[[NKRadarChartDataItem dataItemWithValue:3 description:@"Art"], [NKRadarChartDataItem dataItemWithValue:2 description:@"Math"], [NKRadarChartDataItem dataItemWithValue:8 description:@"Sports"], [NKRadarChartDataItem dataItemWithValue:5 description:@"Liter"], [NKRadarChartDataItem dataItemWithValue:4 description:@"Other"], ]; NKRadarChart *chart = [[NKRadarChart alloc] initWithFrame:frame items:items valueDivider:1]; image = [chart drawImage]; [self.chartImage setImage:image];
